Studdy Solution

STEP 1

Assumptions1. The problem is a mathematical expression −−(−8+9)×−4--(-8+9) \times-4 . We need to simplify this expression3. We will follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often abbreviated as PEMAS.

STEP 2

First, we need to simplify the expression inside the parentheses.
−2−(−8+9)×−4-2-(-8+9) \times-4

STEP 3

Perform the operation inside the parentheses.
−2−(−8+9)=−2−1-2-(-8+9) = -2-1

STEP 4

Now, we need to multiply the result of the parentheses by -4.
−2−1×−4-2-1 \times-4

STEP 5

Perform the multiplication operation.
−2−1×−4=−2−(−4)-2-1 \times-4 = -2-(-4)

STEP 6

Now, we need to perform the subtraction operation.
−2−(−4)-2-(-4)

STEP 7

Perform the subtraction operation.
−2−(−4)=−2+4-2-(-4) = -2+4

STEP 8

Perform the addition operation.
−2+4=2-2+4 =2So, the simplified form of the expression −2−(−8+)×−4-2-(-8+) \times-4 is2.
